Description

백필터용 탈진노즐Dust removal nozzle for bag filter
본 발명은 백필터용 탈진노즐로서, 백필터에 탈진기류를 제공하는 블로우튜브에 형성된 백필터용 탈진노즐에 관한 것이다.The present invention relates to a dust removal nozzle for a bag filter, which is formed in a blow tube for providing a dust escape flow to the bag filter.
통상적으로 공기 중에 존재하는 고체나 액체의 미립자를 제거하기 위한 집진장치의 하나로 백필터(bag filter)를 이용한 집진장치가 있다.In general, there is a dust collector using a bag filter as one of the dust collectors for removing solid or liquid particles present in the air.
백필터를 이용한 집진장치는 대기오염의 원인이 되는 대기 중의 각종 입자상물질이나 공장 등의 배출가스에 포함된 유해 입자를 걸러내거나 배출을 방지하는 대기오염 방지장치의 하나이다.A dust collector using a bag filter is one of the air pollution prevention devices that filter or prevent various particulate matter in the atmosphere that causes air pollution or harmful particles contained in exhaust gas from factories, etc.
이러한 백필터를 이용한 집진장치의 여과방식으로는, 얇은 종이나 섬유 등의 여과재 표면에 먼지를 붙이는 표면여과방식과 유리섬유나 면섬유 같은 두꺼운 층의 여과재를 자루 모양이나 평판형으로 만든 여과포(濾過布), 즉 백필터의 섬유층 속에 먼지를 모으는 내부여과방식이 있다.As a filtration method of a dust collector using such a bag filter, a surface filtration method that attaches dust to the surface of a filter medium such as thin paper or fiber, and a filter cloth made of a thick layer of filter material such as glass fiber or cotton fiber in a bag or flat plate shape ), that is, there is an internal filtration method that collects dust in the fiber layer of the bag filter.
운전초기에는 여과재에 의해서만 먼지가 분리되지만, 시간이 지나면서 여과재의 표면에 쌓이는 분진층이 여과체로서의 역할을 하게 된다.At the beginning of operation, dust is separated only by the filter medium, but over time, the dust layer accumulated on the surface of the filter medium serves as a filter medium.
이와 같이 분진층이 주 여과층으로서의 역할을 하게 되면서 포집효율은 상승하지만 동시에 가스흐름을 방해하는 저항체로서 작용할 수 있다.In this way, as the dust layer acts as the main filtration layer, the collection efficiency increases, but at the same time, it can act as a resistor to block the gas flow.
이와 같은 집진방식은 우수한 집진기술 중 하나로 백필터를 적절히 선택함에 따라 높은 효율을 얻을 수 있지만, 압력손실의 과부하로 인하여 백필터의 세공이 막히게 되면 여과재의 수명이 단축되며 운전비용 상승의 요인이 되기도 한다.This dust collection method is one of the excellent dust collection technologies, and high efficiency can be obtained by properly selecting a bag filter. do.
따라서 백필터 표면의 먼지 층이 지나치게 두꺼워지면 압력손실이 커지므로 어느 정도 사용한 뒤에는 먼지를 털어주는 탈진작업을 해주어야 한다.Therefore, if the dust layer on the surface of the bag filter becomes too thick, the pressure loss increases.
백필터의 탈진작업을 위한 기존 방법으로는 블로우튜브(Blow tube)에서 고압의 탈진기류를 분사노즐을 통해 정기적으로 분사하여 백필터에 포집된 분진을 역세척하는 방법이 사용되고 있다.As an existing method for dust removal of a bag filter, a method of backwashing the dust collected in the bag filter by regularly spraying a high-pressure exhaust stream from a blow tube through a spray nozzle is used.
그런데, 기존의 분사노즐은 블로우튜브에서 공급되는 압축공기만을 분사함에 따라 탈진기류의 유량이 한정되므로 백필터에 포집된 분진을 효과적으로 제거할 수 없는 한계점이 있으며, 이에 따라 탈진기류가 백필터의 내부 표면으로 고르게 전달되지 않음으로써 탈진효율이 저하되는 문제점이 있다.However, since the conventional injection nozzle only sprays compressed air supplied from the blow tube, the flow rate of the exhaust air flow is limited, so there is a limitation in that the dust collected in the bag filter cannot be effectively removed. There is a problem in that the exhaustion efficiency is lowered because it is not transmitted evenly to the surface.
구체적으로, 본 발명의 선행기술로서 대한민국 공개특허공보 제10-2016-0052254호에 제안된 백필터용 탈진노즐이 있다.Specifically, as a prior art of the present invention, there is a dust removal nozzle for a bag filter proposed in Korean Patent Application Laid-Open No. 10-2016-0052254.
이러한 선행기술은 토출관의 하부가 안내관 내에 삽입되는 형태로서, 탈진기류로 인해 발생하는 음압이 토출관 내에 형성하게 되고, 결과적으로 주변공기의 유입이 최대화되지 않는다는 문제점이 있다.This prior art has a problem in that the lower part of the discharge pipe is inserted into the guide pipe, and the negative pressure generated by the escapement air flow is formed in the discharge pipe, and consequently, the inflow of ambient air is not maximized.
또한, 주변공기가 유입될 수 있는 이격공간이 안내관의 최상부, 즉, 토출관에서 나온 탈진기류의 진행방향 뒷부분에만 형성되므로 주변기류의 유입범위가 제한적이라는 문제점이 있다.In addition, since the separation space through which the ambient air can be introduced is formed only at the top of the guide tube, that is, at the rear portion of the exhaust air flow from the discharge tube, there is a problem in that the inflow range of the ambient air flow is limited.
본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 탈진효율을 증대시키는 백필터용 탈진노즐을 제공하는 데에 그 목적이 있다.The present invention has been devised to solve the above problems, and an object of the present invention is to provide a dust removal nozzle for a bag filter that increases the dust removal efficiency.
상기와 같은 목적을 달성하기 위하여 본 발명에 따른 백필터용 탈진노즐은, 블로우튜브의 단부에 형성된 토출관; 및 백필터의 상측에 배치되며, 상기 토출관에 연결되고 상부개구부가 상기 토출관의 하단부로부터 이격된 안내관;을 포함한다.In order to achieve the above object, there is provided a dust removal nozzle for a bag filter according to the present invention, comprising: a discharge pipe formed at an end of a blow tube; and a guide tube disposed above the bag filter, connected to the discharge tube, and having an upper opening spaced apart from the lower end of the discharge tube.
여기에서, 상기 안내관은, 하부개구부가 하측의 상기 백필터와 이격되고, 상기 상부개구부가 상측의 상기 토출관과 이격되어, 상하측으로 모두 이격된 이중 상하이격 배치구조를 이룰 수 있다.Here, in the guide tube, a lower opening portion is spaced apart from the bag filter on the lower side, and the upper opening portion is spaced apart from the discharge tube on the upper side, thereby forming a double vertical spacing structure in which both are spaced apart in the upper and lower sides.
그리고, 상기 안내관은 상측으로 갈수록 확장되는 상부확장부가 형성될 수 있다.In addition, the guide tube may be formed with an upper extension extending toward the upper side.
또한, 상기 안내관은 하측으로 갈수록 확장되는 하부확장부가 형성될 수 있다.In addition, the guide tube may be formed with a lower extension extending toward the lower side.
물론, 상기 안내관은 상측으로 갈수록 확장되는 상부확장부와, 하측으로 갈수록 확장되는 하부확장부가 동시에 형성될 수도 있다.Of course, the guide tube may be simultaneously formed with an upper extension extending toward the upper side and a lower extension extending toward the lower side.
한편, 상기 안내관은 상기 상부확장부와 하부확장부 사이에 종방향으로 내경이 유지되는 중간부가 형성되며, 상기 중간부의 내부에는 회오리형 구조체가 형성될 수 있다.On the other hand, the guide tube is formed with an intermediate portion in which the inner diameter is maintained in the longitudinal direction between the upper extension and the lower extension, and a tornado-type structure may be formed inside the intermediate portion.
이러한 회오리형 구조체는, 복수 개의 돌출판이 상기 중간부의 내부 측면에 배치되며 하측으로 갈수록 회전되는 구조로 이루어질 수 있다.Such a tornado-type structure may have a structure in which a plurality of protruding plates are disposed on the inner side surface of the intermediate part and rotate toward the lower side.
또한, 상기 하부확장부의 내부에는 나선형 구조체가 형성될 수 있다.In addition, a spiral structure may be formed inside the lower extension.
이러한 나선형 구조체는, 한 개의 안내판이 상기 하부확장부의 내부 측면에 배치되며 하측으로 갈수록 회전되는 구조로 이루어질 수 있다.Such a spiral structure may have a structure in which one guide plate is disposed on the inner side of the lower extension and is rotated toward the lower side.
이에 더하여, 상기 하부확장부는 원뿔형 가이드부재가 내장되고, 상기 원뿔형 가이드부재는 상기 하부확장부의 내부 측면과 일정 간격 이격된 배치구조로 이루어질 수 있다.In addition, the lower extension portion may have a built-in conical guide member, and the conical guide member may have an arrangement structure spaced apart from the inner side surface of the lower extension portion by a predetermined interval.

As it increases, it has the effect of increasing the exhaustion efficiency of the bag filter.
나아가, 본 발명은 안내관에 상부확장부와 하부확장부가 형성됨으로써, 안내관 상부에서는 토출관과 안내관 사이의 이격공간에서 하측의 안내관 내부로 유입되는 주변공기의 유입량을 더욱더 증가시킬 수 있고, 안내관 하부에서는 탈진기류를 최대한 분산시킴으로써 백필터의 전체적인 부분에서 탈진작용이 균일하게 이루어지게 할 수 있는 장점을 지닌다.Furthermore, the present invention can further increase the amount of ambient air flowing into the lower guide tube in the space between the discharge tube and the guide tube in the upper portion of the guide tube by forming an upper extension and a lower extension in the guide tube. , it has the advantage that the exhaustion action can be made uniformly in the entire part of the bag filter by dispersing the exhaust air flow as much as possible in the lower part of the guide tube.
이에 더하여, 본 발명은 회오리형 구조체가 형성됨으로써 중간부에서 탈진기류에 회전유동을 발생시키고, 나선형 구조체가 형성됨으로써 하부확장부에서 탈진기류가 회전유동되도록 탈진기류를 가이드함에 따라, 탈진기류가 백필터의 내부에서 하부에 집중되지 않고 균일하게 측부분으로도 통과되도록 하여, 백필터의 손상을 방지하고 탈진효율을 증대시킬 수 있는 이점을 가진다.In addition, the present invention generates a rotational flow in the escapement airflow in the middle part by forming a tornado-type structure, and as a spiral structure is formed to guide the escapement flow so that the escapement airflow is rotated in the lower extension part, the escapement airflow is back It has the advantage of preventing damage to the bag filter and increasing the exhaustion efficiency by allowing it to pass uniformly to the side without being concentrated on the lower part of the filter.
아울러, 본 발명은 하부확장부에 원뿔형 가이드부재가 내장됨으로써, 탈진기류가 하부확장부를 통과 시 하부확장부의 중앙부분만을 집중해서 통과하지 않고 하부확장부의 내측면 측으로 분산시켜 백필터의 전체적인 부분을 균일하게 통과되도록 함에 따라, 백필터의 손상을 방지하고 탈진효율을 증대시킬 수 있는 장점을 가진다.In addition, in the present invention, since the conical guide member is built in the lower extension, when the escaped air flow passes through the lower extension, it does not pass through only the central portion of the lower extension, but disperses it toward the inner surface of the lower extension to uniformly distribute the entire part of the bag filter. It has the advantage of preventing damage to the bag filter and increasing the exhaustion efficiency.

본 발명에 따른 백필터용 탈진노즐은, 도 1 내지 도 9, 도 12 내지 도 14에 도시된 바와 같이, 토출관(100)과, 안내관(200)을 포함한다.As shown in FIGS. 1 to 9 and 12 to 14 , the dust removal nozzle for a bag filter according to the present invention includes a discharge pipe 100 and a guide pipe 200 .
상기 토출관(100)은 블로우튜브(2)의 단부에 형성되며, 블로우튜브(2)를 통해 공급되는 압축공기가 이러한 토출관(100)을 통해 백필터(1) 측으로 토출된다.The discharge pipe 100 is formed at the end of the blow tube 2 , and compressed air supplied through the blow tube 2 is discharged toward the bag filter 1 through the discharge pipe 100 .
그리고, 상기 안내관(200)은 토출관(100)에 연결부재(190)에 의해 연결되어 백필터(1) 측으로 연장된 구조를 취한다.In addition, the guide tube 200 is connected to the discharge tube 100 by a connection member 190 to extend toward the bag filter 1 .
이러한 안내관(200)은 토출관(100)을 통해 토출된 압축공기를 백필터(1) 측으로 가이드하는데, 아울러 토출관(100)의 주변기류를 유입시켜 토출관(100)의 압축공기와 함께 백필터(1)로 안내함으로써, 백필터(1)에 대한 탈진기류의 유량을 늘리는 역할을 수행한다.The guide pipe 200 guides the compressed air discharged through the discharge pipe 100 to the bag filter 1 side, and also introduces a peripheral airflow of the discharge pipe 100 together with the compressed air of the discharge pipe 100 . By guiding to the bag filter (1), it serves to increase the flow rate of the escape air flow to the bag filter (1).
본 발명의 구성적 특징으로서 안내관(200)은 백필터(1)의 상측에 배치된 상태에서, 상부개구부(200a)가 토출관(100)의 하단부로부터 이격된 구조를 취할 수 있다.As a structural feature of the present invention, the guide tube 200 may have a structure in which the upper opening 200a is spaced apart from the lower end of the discharge tube 100 while the guide tube 200 is disposed on the upper side of the bag filter 1 .
즉, 토출관(100)의 하단부가 안내관(200)의 상부개구부(200a)로 인입되어 안내관(200)에 수용되지 않고, 토출관(100)의 하단부와 안내관(200)의 상부개구부(200a)가 서로 이격되어 토출관(100)과 안내관(200) 사이에 일정 정도의 이격공간이 형성된다.That is, the lower end of the discharge tube 100 is introduced into the upper opening 200a of the guide tube 200 and is not accommodated in the guide tube 200 , but the lower end of the discharge tube 100 and the upper opening of the guide tube 200 . (200a) are spaced apart from each other to form a space with a certain degree of separation between the discharge pipe 100 and the guide pipe (200).
이에 따라, 토출관의 하부가 안내관에 수용된 종래구조에 비하여, 본 발명에서의 토출관(100)과 안내관(200)의 이격구조는, 토출관(100)의 압축공기 토출에 의해 발생하는 음압공간의 외부 노출영역이 커지도록 함으로써, 안내관(200) 내부로의 주변공기 유입이 보다 원활하게 이루어지게 할 수 있다.Accordingly, compared to the conventional structure in which the lower part of the discharge pipe is accommodated in the guide pipe, the spaced structure between the discharge pipe 100 and the guide pipe 200 in the present invention is generated by the compressed air discharge of the discharge pipe 100 . By making the external exposure area of the negative pressure space larger, the inflow of ambient air into the guide tube 200 can be made more smoothly.
본 발명은 이와 같이 안내관(200) 내부로의 주변공기 유입이 종래에 비하여 보다 원활하게 이루어져서 주변공기 유입량이 늘어나게 됨으로써, 백필터(1)에 대한 탈진기류의 유량을 더욱 늘림에 따라, 백필터(1)에 대한 탈진효율을 증대시킬 수 있다.As described above, in the present invention, the inflow of ambient air into the guide tube 200 is made more smoothly than in the prior art, and the inflow of ambient air is increased. It is possible to increase the exhaustion efficiency for (1).
구체적으로, 상기 안내관(200)은 이중 상하이격 배치구조를 취할 수 있다.Specifically, the guide tube 200 may take a double vertical spacing structure.
즉, 안내관(200)은 하부개구부가 하측의 백필터(1)와 이격되고, 상부개구부(200a)가 상측의 토출관(100)과 이격되어, 상하측으로 모두 이격된 이중 상하이격 배치구조를 이루게 된다.That is, in the guide tube 200, the lower opening is spaced apart from the bag filter 1 on the lower side, and the upper opening 200a is spaced apart from the discharge tube 100 on the upper side. will achieve
이와 같이 안내관(200)은 상측의 토출관(100)과 이격된 구조에 더하여, 하측의 백필터(1)와도 이격되어, 안내관(200)의 상측과 하측 모두에 이격공간이 형성되는 이중 상하이격 배치구조를 취함으로써, 토출관(100)을 통해 토출된 압축공기에 의한 음압공간이 안내관(200)의 상측 이격공간과 하측 이격공간 모두에서 외부에 노출되어 외부 노출영역이 더욱더 커지게 된다.In this way, the guide tube 200 is spaced apart from the lower bag filter 1 in addition to the structure spaced apart from the upper discharge tube 100 , so that a spaced space is formed on both the upper and lower sides of the guide tube 200 . By taking the vertical spacing structure, the negative pressure space by the compressed air discharged through the discharge pipe 100 is exposed to the outside in both the upper spaced space and the lower spaced space of the guide tube 200, so that the external exposure area becomes larger. do.
이로 인하여, 안내관(200)의 상측 이격공간과 함께 하측 이격공간에서도 주변공기의 유입이 이루어져서 백필터(1)에 대한 탈진기류의 유량을 더욱더 늘릴 수 있음에 따라, 백필터(1)에 대한 탈진효율을 더욱 증대시킬 수 있다.Due to this, the flow rate of the escapement air flow to the bag filter 1 can be further increased because the inflow of ambient air is made in the lower spaced space as well as the upper spaced space of the guide tube 200. It is possible to further increase the exhaustion efficiency.
상술된 바와 같은 본 발명은 안내관(200)의 형상에 따라 여러 가지 실시예를 포함할 수 있다.The present invention as described above may include various embodiments according to the shape of the guide tube 200 .
먼저, 본 발명은 제1 실시예로서 도 1 및 도 2에 도시된 바와 같이, 안내관(200)이 기본적인 형상으로서 튜브 형상을 취할 수 있다.First, as shown in FIGS. 1 and 2 as a first embodiment of the present invention, the guide tube 200 may take a tube shape as a basic shape.
또한, 본 발명은 제2 실시예로서 도 3 및 도 4에 도시된 바와 같이, 안내관(200)의 상부가 확장되는 구조를 취할 수 있다.In addition, the present invention may take a structure in which the upper portion of the guide tube 200 is expanded, as shown in FIGS. 3 and 4 as a second embodiment.
즉, 안내관(200)은 상측으로 갈수록 확장되는 상부확장부(210)가 형성될 수 있다.That is, the guide tube 200 may be formed with an upper extension portion 210 that expands toward the upper side.
제1 실시예에서의 안내관(200)이 종방향으로 일정하게 유지되는 횡단면적 구조를 가진 것에 비하여, 제2 실시예에서의 상부확장부(210)는 상측으로 갈수록 단면적이 커지는 구조를 가짐에 따라, 토출관(100)과 안내관(200) 사이의 이격공간에서 하측의 안내관(200) 내부로 유입되는 주변공기의 유입량을 더욱더 증가시킬 수 있다.Compared to the guide tube 200 in the first embodiment having a cross-sectional structure that is kept constant in the longitudinal direction, the upper extension 210 in the second embodiment has a structure in which the cross-sectional area increases toward the upper side. Accordingly, it is possible to further increase the amount of ambient air flowing into the lower guide tube 200 in the space between the discharge tube 100 and the guide tube 200 .
그리고, 본 발명은 제3 실시예로서 도 5 및 도 6에 도시된 바와 같이, 안내관(200)의 하부가 확장되는 구조를 취할 수 있다.And, as shown in FIGS. 5 and 6 as a third embodiment of the present invention, the lower portion of the guide tube 200 may be expanded.
즉, 안내관(200)은 하측으로 갈수록 확장되는 하부확장부(230)가 형성될 수 있다.That is, the guide tube 200 may be formed with a lower extension portion 230 that expands toward the lower side.
제1 실시예에서의 안내관(200)이 종방향으로 일정하게 유지되는 횡단면적 구조를 가진 것에 비하여, 제3 실시예에서의 하부확장부(230)는 하측으로 갈수록 단면적이 커지는 구조를 가짐에 따라, 백필터(1)로 안내하는 탈진기류를 최대한 분산시킴으로써 백필터(1)의 전체적인 부분에서 탈진작용이 균일하게 이루어지게 할 수 있다.Compared to the guide tube 200 in the first embodiment having a cross-sectional structure that is kept constant in the longitudinal direction, the lower extension 230 in the third embodiment has a structure in which the cross-sectional area increases toward the lower side. Accordingly, the exhaustion action can be made uniformly in the entire part of the bag filter 1 by dispersing the exhaust air flow guided to the bag filter 1 as much as possible.
아울러, 본 발명은 제4 실시예로서 도 7 및 도 8에 도시된 바와 같이, 안내관(200)의 상부와 하부가 확장되는 구조를 취할 수 있다.In addition, the present invention may take a structure in which the upper and lower portions of the guide tube 200 are expanded as shown in FIGS. 7 and 8 as a fourth embodiment.
즉, 안내관(200)은 상측으로 갈수록 확장되는 상부확장부(210)가 형성되고, 하측으로 갈수록 확장되는 하부확장부(230)가 형성될 수 있다.That is, the guide tube 200 may be formed with an upper extension 210 that expands toward the upper side, and a lower extension 230 that extends toward the lower side.
제1 실시예에서의 안내관(200)이 종방향으로 일정하게 유지되는 횡단면적 구조를 가진 것에 비하여, 제4 실시예에서의 상부확장부(210)와 하부확장부(230)는 안내관(200)이 상측과 하측으로 갈수록 단면적이 커지는 구조를 가지도록 함에 따라, 안내관(200) 상부에서는 토출관(100)과 안내관(200) 사이의 이격공간에서 하측의 안내관(200) 내부로 유입되는 주변공기의 유입량을 더욱더 증가시킬 수 있고, 안내관(200) 하부에서는 탈진기류를 최대한 분산시킴으로써 백필터(1)의 전체적인 부분에서 탈진작용이 균일하게 이루어지게 할 수 있다.While the guide tube 200 in the first embodiment has a cross-sectional structure that is kept constant in the longitudinal direction, the upper extension 210 and the lower extension 230 in the fourth embodiment have a guide tube ( As the 200) has a structure in which the cross-sectional area increases toward the upper side and the lower side, the upper guide tube 200 moves from the space between the discharge tube 100 and the guide tube 200 to the lower guide tube 200 inside. It is possible to further increase the amount of ambient air introduced therein, and by dispersing the exhaust air flow in the lower part of the guide tube 200 as much as possible, the exhaustion action can be made uniformly in the entire part of the bag filter 1 .
한편, 상기 토출관(100)은 도 9에 도시된 바와 같이, 하부가 하측으로 테이퍼진 구조로 이루어질 수 있다.Meanwhile, as shown in FIG. 9 , the discharge pipe 100 may have a structure in which the lower part is tapered downward.
이와 같이 토출관(100)의 하부가 하측으로 갈수록 협소해지는 구조를 지님으로써, 토출관(100)에서 토출되는 압축공기의 유속을 증가시켜서 토출관(100)과 안내관(200) 사이의 이격공간에서의 음압을 높일 수 있으며, 이에 따라 안내관(200) 내부로 유입되는 주변공기의 유량을 늘려서 종국적으로 탈진효율을 높일 수 있다.As such, by having a structure in which the lower portion of the discharge pipe 100 becomes narrower toward the lower side, the flow rate of the compressed air discharged from the discharge pipe 100 is increased to increase the separation space between the discharge pipe 100 and the guide pipe 200 . It is possible to increase the negative pressure in the , and thus the flow rate of the ambient air flowing into the guide tube 200 can be increased to ultimately increase the exhaustion efficiency.
도 10 및 도 11은 백필터(1)의 탈진공정 후 집진기의 차압을 나타낸 그래프이다.10 and 11 are graphs showing the differential pressure of the dust collector after the dust removal process of the bag filter (1).
도면을 참조하면, 탈진효율을 알기 위해 집진성능과 관련된 수치로서, 백필터(1)의 탈진공정 후 집진기의 차압수치를 나타내었는데, 이때 집진기에서 집진 시 백필터(1)로 유입되는 유입경로와 백필터(1)에 의해 필터링되어 백필터(1)로부터 나가는 유출경로 각각에 압력계를 장착하여, 집진기의 차압수치가 측정되었다.Referring to the drawings, as a numerical value related to the dust collection performance in order to know the dust removal efficiency, the differential pressure value of the dust collector after the dust removal process of the bag filter 1 is shown. A pressure gauge was installed in each of the outlet paths filtered by the bag filter (1) and exiting the bag filter (1), and the differential pressure value of the dust collector was measured.
구체적으로, 30분 동안 균일하게 먼지를 주입한 다음, 블로우튜브(2)를 통해 압축공기를 공급하여 탈진공정이 수행된 후, 백필터(1)에 걸리는 차압을 측정하였다.Specifically, dust was uniformly injected for 30 minutes, and then compressed air was supplied through the blow tube (2) to perform the dedusting process, and then the differential pressure applied to the bag filter (1) was measured.
먼저, 도 10에서는 본 발명의 제1 실시예를 다른 비교예들과 비교하였는데, 비교예로서 안내관이 없이 토출관만 있는 경우(튜브형), 그리고 토출관의 하부가 안내관에 삽입된 경우(토출관 삽입형)와 비교하였다.First, in FIG. 10, the first embodiment of the present invention was compared with other comparative examples. As a comparative example, when there is only a discharge tube without a guide tube (tube type), and when the lower part of the discharge tube is inserted into the guide tube ( discharge tube insertion type).
결과로서, 튜브형은 탈진공정 회수가 늘어날수록 차압이 상당히 커진데 반하여, 토출관 삽입형과 제1 실시예는 차압이 서서히 증가함을 보여주며, 구체적으로 본 발명의 제1 실시예가 토출관 삽입형보다 차압 증가율이 떨어짐에 따라 탈진효율이 더 우수함을 알 수 있다.As a result, the tubular type shows that the differential pressure increases significantly as the number of times of the dedusting process increases, whereas the discharge tube insertion type and the first embodiment show that the differential pressure gradually increases. As the increase rate decreases, it can be seen that the exhaustion efficiency is better.
또한, 도 11에서는 본 발명의 제1 실시예 내지 제4 실시예를 비교하였는데, 제1 실시예 < 제3 실시예 < 제2 실시예 < 제4 실시예와 같은 순서로서, 제4 실시예의 탈진효율이 가장 우수하다는 것을 알 수 있다.In addition, in FIG. 11, Examples 1 to 4 of the present invention were compared, in the same order as Example 1 < Example 3 < Example 2 < Example 4, and exhaustion of Example 4 It can be seen that the efficiency is the best.
한편, 본 발명의 상술된 실시예들에 더하여, 탈진효율을 더욱 증대시킬 수 있도록 추가적인 구성을 포함할 수 있다.On the other hand, in addition to the above-described embodiments of the present invention, it may include an additional configuration to further increase the exhaustion efficiency.
일례로서 탈진효율이 가장 우수한 제4 실시예에 추가적인 구성을 포함시키면 다음과 같다.As an example, if an additional configuration is included in the fourth embodiment, which has the most excellent exhaustion efficiency, as follows.
도 12는 도 7의 백필터용 탈진노즐에 회오리형 구조체가 형성된 것을 나타낸 도면이고, 도 13은 도 7의 백필터용 탈진노즐에 나선형 구조체가 형성된 것을 나타낸 도면이며, 도 14는 도 7의 백필터용 탈진노즐에 원뿔형 가이드부재가 내장된 것을 나타낸 도면이다.12 is a view showing that a tornado-type structure is formed in the dust removal nozzle for the bag filter of FIG. 7, FIG. 13 is a view showing that a spiral structure is formed in the dust removal nozzle for the bag filter of FIG. 7, and FIG. 14 is the bag of FIG. It is a view showing that the conical guide member is built in the dust removal nozzle for the filter.
토출관(100)으로부터 압축공기가 토출되면 안내관(200)을 통해 주변공기가 합류되어, 백필터(1)로 공급되는 탈진기류가 만들어지는데, 이러한 탈진기류가 수직유동(하측으로 직선형 유동)으로 백필터(1)에 공급되면, 백필터(1)가 손상되고 백필터(1)의 탈진효율이 저감될 수 있다.When compressed air is discharged from the discharge pipe 100, the surrounding air is joined through the guide pipe 200 to create an escape air flow that is supplied to the bag filter 1, and this escape air flow is a vertical flow (a straight flow downward). is supplied to the bag filter 1 , the bag filter 1 may be damaged and the exhaustion efficiency of the bag filter 1 may be reduced.
구체적으로, 집진기를 얼마 정도의 기간 동안 사용하게 되면, 그 기간 동안 탈진공정 시 수직유동되는 탈진기류에 의해 백필터(1)의 중앙부가 집중하중을 받게 되는데, 이러한 편중된 탈진기류의 압력에 의해 백필터(1)의 내부에서 중앙 하부 부위에 파공이 쉽게 발생할 수 있다.Specifically, when the dust collector is used for a certain period of time, the central part of the bag filter 1 receives a concentrated load by the exhaust air flow that flows vertically during the dust removal process during that period. A hole may easily occur in the central lower part of the inside of the bag filter 1 .
또한, 수직유동되는 탈진기류는 압력이 상당히 크기 때문에, 백필터(1)의 내부공간에 음압을 형성시킴에 따라, 탈진기류에 의해 백필터(1)로부터 바깥쪽으로 떨어진 먼지들 중 일부가 백필터(1) 내부의 음압에 의해 다시 역으로 백필터(1)에 부착될 수 있다.In addition, since the pressure of the escapement flow that flows vertically is quite large, as a negative pressure is formed in the inner space of the bag filter 1, some of the dust that has fallen outward from the bag filter 1 by the escape flow is removed from the bag filter. (1) It can be attached to the bag filter (1) in reverse again by the internal negative pressure.
상술된 점들을 방지하기 위해, 본 발명은 백필터(1)에 유입되는 탈진기류가 수직유동이 아닌 회전유동하면서 백필터(1)의 전체적인 부분에 균일하게 퍼질 수 있도록 구성될 수 있다.In order to prevent the above-mentioned points, the present invention may be configured such that the exhaust air flow flowing into the bag filter 1 is uniformly spread over the entire part of the bag filter 1 while rotating instead of vertically.

Alternatively, it may be installed inside the intermediate portion 220 as a separate member from the intermediate portion 220 .
이와 같은 회오리형 구조체(310)는 탈진기류가 안내관(200)의 중간부(220)를 통과할 때 탈진기류에 회전유동을 발생시킴으로써, 탈진기류가 하부확장부(230)에서 측방향으로 퍼지게 됨에 따라, 탈진기류가 백필터(1)의 내부에서 하부에 집중되지 않고 균일하게 측부분으로도 통과되도록 하여, 백필터(1)의 손상을 방지하고 탈진효율을 증대시킬 수 있다.This tornado-type structure 310 generates a rotational flow in the escapement airflow when the escapement airflow passes through the middle part 220 of the guide tube 200, so that the escapement airflow spreads laterally in the lower extension part 230. Accordingly, the exhaust air flow is uniformly passed through the side portion without being concentrated in the lower part of the bag filter 1, thereby preventing damage to the bag filter 1 and increasing the exhaustion efficiency.

As it spreads laterally, it is possible to prevent the damage to the bag filter 1 and increase the exhaustion efficiency by allowing the exhaust air flow to pass through the side portion uniformly without being concentrated in the lower portion inside the bag filter 1 . .
